摘要
针对两种应用于双馈风力发电系统机侧最大功率追踪控制的传统控制策略的特点,提出了一种双模控制方法。首先对直接速度控制方式(DSC)与间接速度控制方式(ISC)进行了分析,通过对比分析得到两种控制方式各自的优缺点。在此基础之上,采用双模控制的思想,通过设计切换规则,将DSC与ISC两种控制方式的优势进行了结合,并将这种双模控制方法应用于双馈风力发电系统机侧最大功率追踪控制中。仿真结果验证了双模控制方法可以将两种传统方法的优点进行结合,使控制性能得到提高。
In allusion to two kinds of traditional maximum power point tracking control strategies used in machine side control of doubly fed wind power generation system, an improved dual-mode control method was presented. First,the traditional direct speed control and the indirect speed control were analyzed by comparing the advantages and disadvantages of two control modes, on this basis, the switching rules of dual-mode control was designed and used into the improved method of machine side maximum power point tracking control system. Simulation results show that the improved method can combines the advantages of traditional maximum power point tracking control strategies, which makes the control performance changed for the better.
